Assault Trooper.

The assault trooper is an expert at guerilla warfare, exceeding the potential of the common soldier. They attack with ruthless brutality and manage to take squads on there own. Not as willing to wear the hefty armor of the soldier, they wear light robes in order to advance at incredible speed. Lastly they rely on heavy firepower, ranging from the "The Scrounger" "Triple" "The Old Schooler" but if in dire need to kill the enemy, they will resort in taking weapons from anyone. This is both unconventional for the Natives and the Invading Force.
